Product Overview
The wide body, low-pitch blades of the SP120 fans combined with the custom housing provides outstanding static pressure and airflow through heatsinks or radiators. With rubberized corners, a quiet and reliable Advanced Hydraulic Bearing, and PWM support for increased fan speed control, the SP120 truly is the strong, silent type.

Included in the box are the three user-replaceable colored rings, in red, blue, and white, so you can customize your fan to match your case’s components. Each fan also features blacked-out wires and connectors, so your build looks elegant and clean when done. Available in single and twin packs.Features
• The SP120 High Performance Edition, at full RPM, has outstanding static pressure, up to 3.1mm/H2O, when used on a radiator or heatsink.• 4-PIN PWM Support for increased fan speed control• Seven wide body, low-pitch custom blades for optimal static pressure at very low noise levels.• Custom fan enclosure for ducting air in the right direction with minimal interference.• Advanced Hydraulic Bearing for reliable, quiet operation.• Rubberized corners for sound damping when installed with standard screws.• User-replaceable colored rings so you can match your fans to your case

The modern PC is potentially a mass of heat output and heat production hot spots. With CPUs rated at more than 100W of heat output, single graphics boards carrying similar ratings (and people want to run two!), multiple hard drives the norm, lots of memory and mainboards covered in heatpipes to combat toasty core logic and PWM circuits, a PC appreciably warming up a room when it’s working hard is no joke.

Watercooling for the PC has been around for years in some form or another, for at least as long as Scan have been in business, with basic physics defining why you want to use it. That means for air cooling, to cope with increasing temperature in the heatsink you need to move the air across it faster. That is why thermostatically controlled fans in your PC will turn faster the hotter something gets.

Anybody who has been near their share of computer systems will appreciate that not all systems make the same amount of noise. There are a number of reasons for why this is so. Firstly, a computer makes noise for different reasons. Generally, anything mechanical is going to make noise.
